tinySA-H4

 

I transfer tinySA firmware to NanoVNA-H4 platform
Now possible use H4 platform (STM32F303 CPU + 4` display module) for next tinySA generation

You can flash it to H4 and see how it work (yes no any tinySA hardware on H4, and you not see spectre, but all menus work, sweep times and e.t.c)

H4 allow SD card, so in next tinySA possible save something to it

PS STM32F303 have hardware FPU, and in it SI4432 run on hardware SPI mode, so it allow moew fast work, minimum Zero Span time = 700us, also values convert (if use Volt for example) less slowdown.

Interesting.?

Are you saying that it may be possible to piggyback a SI4432 module to the H4 so we can play more with the FW?

Yes it possible, but not need. This firmware need only as first step for move tinySA on new hardware (use STM32F303 and more bigger display module). Now possible produce tinySA based on H4 hardware (before use H hardware, but it have some limits, like no FPU, less flash size)

PS yes exist H4+ one SI4432 module as proto-board, but it used as signal generator only.
